A flip where the construction had to hold
The Liberty City Flip was a single-family house of roughly 1,150 square feet that an investor bought to renovate and resell. The math on the acquisition was not generous. The basis only worked if two things happened at once: construction had to come in on the number that was underwritten, and the finished house had to show well enough to actually reach the resale comp the investor was betting on. There was no cushion for a surprise, and no cushion for a slow trade.
That is the real condition of most flips in Miami-Dade, and it is why the general contractor selection matters more here than on almost any other kind of job. On an owner-occupied remodel, a two-week delay is an inconvenience. On a flip, it is carrying cost against a fixed exit. We took this project on as the investor’s general contractor with a nine-week schedule and a scope that had already been priced against the underwriting. It sold. It came in on budget and on time, with no change orders and no slipped weeks.
Scope gets locked to the underwriting before demo starts
The single most common way a Miami flip goes sideways is that the scope was never really written down. An investor buys on a walkthrough and a rough number, a crew starts opening walls, and the scope grows one conversation at a time until the budget the deal was built on no longer exists. By the time anyone notices, the money is spent and the only lever left is the sale price.
We work the opposite direction. Before demolition, we take the investor’s underwriting and turn it into a line-item scope: every room, every finish category, every allowance, with the exclusions stated in writing. If the deal was underwritten to a certain level of finish, the scope says exactly what that level of finish is. If something the investor wants is not in the number, we say so in preconstruction rather than discovering it in week five. That document becomes the contract, the schedule basis, and the yardstick we get measured against. It is the same discipline we bring to every investment and repositioning engagement, whether the asset is a single house or a small portfolio.
Why the pre-demo walk matters more than the design
On a flip, the design decisions are usually straightforward. The risk sits in the things you cannot see from the driveway: the age of the electrical, the condition of the drain lines, whether the roof and the window openings are going to hold up under permit review. We walk those items deliberately before we price the job, because those are the discoveries that stretch a nine-week schedule into something the deal was never underwritten for. Naming them up front lets the investor decide whether the deal still works, while the decision is still cheap.
How long does a fix and flip renovation take in Miami?
This Liberty City flip was delivered on a nine-week schedule from demolition through final cleaning. On a Miami-Dade flip the schedule follows the scope rather than the square footage: work that stays inside the existing footprint and leaves structure, service size and the roof alone moves fastest.
Most of that work can be sequenced by trade without waiting on inspections that gate everything behind them. Add a load-bearing change, a panel upgrade or a re-pipe and the schedule stretches.
The other variable is decision speed. Flip schedules break far more often on selection delays than on labor. When cabinetry, tile, plumbing fixtures, and flooring are all selected and released before demolition, the trades never wait on a material call. On this project every finish was locked during preconstruction, which is the main reason nine weeks stayed nine weeks.
- Fastest: interior cosmetic reset, no structural or service changes
- Middle: kitchen and bath rebuilds with new plumbing fixtures in existing locations
- Longest: structural changes, roof work, or electrical service upgrades that gate inspections
The scope that actually moved the resale comp
Not every dollar in a flip does the same work. Buyers walking a house in Liberty City form an opinion almost immediately, and that opinion is driven by a short list of things: how bright the house feels, whether the kitchen looks new, whether the bathrooms look clean, and whether the floors run uninterrupted. We built the scope around that list.
- A new kitchen with white shaker cabinetry, stone-look counters, and stainless appliances — the single highest-visibility room in the house
- Both bathrooms rebuilt with fresh tile surrounds and modern fixtures, because a dated bathroom reads as deferred maintenance to a buyer
- Durable wood-look plank flooring throughout, run continuously so the plan feels larger than its square footage
- New interior and exterior paint in a bright, clean palette to lift every photo in the listing
- Updated lighting and hardware, which is inexpensive relative to its effect and makes the rest of the finishes read as intentional
- Drive, fencing, and landscaping tidied so the first listing photo leads with curb appeal
What is not on that list matters too. We did not spend the investor’s money on custom millwork, imported stone, or specification-grade appliances that a buyer in this comp set will not pay a premium for. That restraint is not cost-cutting; it is matching the finish level to the exit. We take the same view on luxury residential work in the other direction: the finish should match what the property and the buyer actually justify, and nothing above or below it.
How do you keep a flip renovation on budget in Miami-Dade?
You keep a Miami-Dade flip on budget by pricing the full scope line-item before demolition, releasing every finish selection in preconstruction, and holding the scope fixed once work starts, so a change order becomes something the investor chooses rather than something the job springs on them.
Budget overruns on flips come from three places, in this order: scope creep, discovery, and delay. Scope creep is the controllable one, and it is controlled by writing the scope down in enough detail that additions are visible as additions. When the contract says exactly which rooms get which finishes, an owner can still choose to add work — but they see the cost before it is committed rather than after.
Discovery is handled by looking before you price. Opening a few strategic areas and checking the mechanical, electrical, and plumbing condition during preconstruction converts unknowns into either line items or written exclusions. Delay is handled by procurement: materials on site before the trade that installs them arrives. On this project there were no change orders, and the job closed on the original number.
- Line-item scope tied to the underwriting, not a lump-sum guess
- All finishes selected and ordered before demolition
- Written exclusions so nothing is assumed included
- One point of accountability for schedule and cost
Curb appeal is a line item, not an afterthought
Investors routinely underfund the exterior, then wonder why showings are slow. The listing photo that appears first in a search result is almost always the front of the house, and a buyer who scrolls past it never sees the new kitchen. On this project the drive, the fencing, and the landscaping were part of the scope from the beginning, scheduled and budgeted like any other trade. Exterior paint in a clean palette, a tidy fence line, and cut-back landscaping cost very little relative to the kitchen, and they determine how many people walk through the door.
That sequencing matters as much as the work itself. Exterior finishing is scheduled so it completes alongside the interior, not after it, which means the house is photograph-ready the day it is done rather than two weeks later. For investors working across Liberty City and the surrounding neighborhoods, that difference is real carrying cost.
Should I renovate a flip before or after closing on the property?
Renovate after you close and control the property, but do the scoping, pricing, and finish selection before closing so demolition can start the week you take title with a fixed budget already in place.
Construction on a property you do not yet own is the seller’s decision to grant, not yours to make, and it is rarely worth the conversation. What you can do without owning anything is the paperwork. Schedule pressure on a flip starts the day you take title, so the preconstruction work should be finished before then — and a walkthrough during the inspection period is enough to build a real line-item scope and get it priced.
The practical version of this is simple: use the contract period to have your contractor walk the property, write the scope, confirm what the permit path looks like, and release the finish selections. Then closing day and demolition day can be the same week. That single change is one of the most reliable ways to take carrying cost out of a flip.
The exit
The house was delivered on budget and on the nine-week schedule, and sold. From the investor’s side, the outcome that mattered was not any single finish decision — it was that the construction number they underwrote was the construction number they paid, and the week they planned to list was the week they listed. On a thin basis, that is the part a contractor actually controls.
If you are underwriting a flip anywhere in Miami-Dade and need construction priced against your model rather than against a guess, that is the work we do. Bring us the property during your inspection period and we will give you a scope you can actually underwrite to, then build to it. You can request a proposal with the address and your target finish level, or look at how the same approach played out on the Westchester value-add.
